. 'GAL KING-MACHINE.

T 0 all whom it may concern Be it known that I, HENRY BBElVlTNER, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of 65 Marlborough avenue, Broomhill, Glasgow, Scotland, electrical engineer, have 1nvented a certain new and useful Improved Calking-Machine, of which the following is a specification. a

This invention relates to a machine for calking or packing seams, joints, slots or grooves and .is particularly applicable for use in calking deck seams "or floor omts, more especially in ships decks, but it wlll be understood that theinventionmay be utilized for calking or packing any similar type of scam, joint, slot or groove. 7

Heretofore, in packing seams or joints of this nature, difficulty has been experienced owing to the narrowness of the slot or groove and the considerably greater dimensions of the resilient or compressible packing employed, which is usually oakum in the case of ships deck seams. It is the principal object of the present invention to overcome this difficulty and to enable comparatively narrow seams or joints, to be readily and efliciently packed with resilient or compressible packing which may be of normally considerably greater dimensions. A further object is to enable the calking or packing to be effected more rapidly and economically by dispensing with the usual hand labor. 7

According to the present invention, an enlarged seam is formed by fitting an extension or guideway to the seam or space to be packed, so that it forms an outward extension or continuation thereof, the walls of which preferably taper toward the seam and are flush therewith.

Thepacking'is supplied to this enlarged seam and rammed into its narrow extremity by a reciprocatory calking tool or hammer. The packing may be supplied to the seam extension in an uncompressed state and will 7 be gradually compressed as it traverses through the enlarged seam, this compression being effected between the tapered walls of the seam extension under the pressure of the calking tool and. the drag of the packing through the seam extension, the compression gradually increasing as the packing traverses into place and the packing. reaching the space to be packed in a partially compressed state in which it can be eifectively and solidly rammed into place by the point of the tool.

Application filed May 11,1920. Serial No. 380,680. r

The calking machine comprises essentially a-vertically reciprocated calking tool, means ing one construction of the machine by way ofexample.

Figures 1, 2 and 3 are end, side and plan views respectively of the complete machine.

Fig. 4 is an end view and Fig. 5 a plan view of the carriage or crawling gear.

Fig. 6 is a detail side view of the calking tool and adjacent mechanism. Fig. 7 is an edge view of the calking tool. Fig. 8 is an inverted plan view, and Fig. 9 an end view of-the parts seen in Fig. -6. Fig. 10 is a dezail1 view of the guide block for the calking 00 i i a The seams or-joints 1 of the deck or floor boards Qto be packed are shown in Fig. 2.

-Fitted over the seam 1 is a funnel or taso that the opening 4 forms an outward en larged seam extension or continuation of the seam.

The packing is supplied to the seam extension 4 (as hereinafter described) and is rammed into the seam 1 by means of a reciprocatory calking tool or hammer 5, which is preferably wedge-shaped (as seen in Fig. 7) to correspond to the taper of the seam extension 4. The edge 5 of the tool 5 may be plain, or serrated so as 'to exert a pull upon the packing. The tool 5 is preferably tapered downwardly in both directions, forming inclined edges 5, so that the point of the tool extends into the joint 1 when the tool descends, the front edge 5 bearing against the packing. v

The packing may be supplied to the seam extension '4. in an uncompressed state and will be gradually compressed between the tapered walls of the seam extension 4 under the pressure of the calking tool 5, the packing being continuously compressed as it is moved through the seam extension 4, reachingthe seam 1 in a state in which it can be effectively by the point of the tool5.

spaced apart by central blocks 6 and intermediate plates 7 thelatter forming-the sides 7 of the seam extension 4 and the blocks 6 having a curved inner profile 6 forming a 6 soas to rest on the deck and lift the are'adapted to be traversed alongthe seam to the seam by the downward and forward guide or runway for the packingwhich is 1 sothat the packing is fed automatically pressure of thejcalking tool 5 against the packing and by the retention of the-latter by compression in thejoint.

Similar seam extensions are preferably fitted both in front'o'f and in' rear' of'thetool 5( as seenin Fig. 6) 'so that the machine may betraversed in either direction. The seam extensions may be bolted together by bolts 8 and resiliently supported by vertically movable supports; 9 fromthe gear casing 10; If, desired, theiseam extensions maybe guided at one or bothends by a roller or rollers or'their equivalent, adapted to;-run

in the seam 1 and thus maintain the seam" extension in alinement with the'joint 1. It

will be readily understood that-the supports 9 may be adjusted verticallywith'respect to the gear casing 10 and may be fitted with springs ll'so as to provide both positive and automatic vertical adjustment of the seam extensions; 7 I e The calking tool 5 is preferably power 1 driven and of ad'ustable-stroke for which purpose it maybe fixed Within a block 12 (shown in plan in Fig. 10) said'block being guided in fixed vertical guides 13 (Fig. 6).

and being jointed to a link 14 pivoted to the ends of links15 and 16, the link 15 bein pivoted at its other end to the flywheel 1?; I which is driven by the electro motor or other prime mover 18 (Figs. 1, 2 and3). The free end of the link 16 has apin 19 working with-- in a slot 20 (Fig. 1) in the gear caselO and is connected to one end of a combined hand r and foot adjusting lever 22; By adjusting i 7 its stroke.

the latter in any required position, the links 14 and 15 maybe moved more or less out of alinement with each other, thus varying the lowermost position of the tool and varying It will be seen that the 'mechanisni'ijust described enables the tool 5 to be lifted'clear' of'the' deck or'fioor after each stroke, and to clear" itself of threads "from the packing.

Any other: adjustable stroke mechanism may,howevelg-gbe employedgand if desired, the tool maybe of the-drop-hammer type and solidly rammed into place;

and controlled by springs, or weights to ine crease the downward pressure. 1 I

As shown in Figs. 6, 3 and 9, the parallel members 3 of the seam extension may be The seam extensions insure that the tool properly engages the seam 1 during each downstroke, but this may be'further insured, if desired, .by making the plates 7 project into the seam land the maylbe' spring pressed toiward tlieitool (1f required) so as to be kept in close contact therewith, V g V The oakum or likej-pa'ckingis preferably mounted upon a reel or reels 23 (Figs. 1 and 2) supported in" any convenient "position 7 upon asuitable carriage 24 (Figsg4-and5) -which carries the motor, the calking' tool and seam extensions. The packing 25 (Fig. 1) ;may be supplied to the seam extension 4 over afguide roller 26 and-suitable guides,

the roller 26 being adapted to be swung fromone side of the machin'e to the other (as indi-- cated in dotted lines in Fig. 1') 15 as to feed the packing to either side of the tool 5.

The carriage 24 is fitted with, crawling gear or likem'echanism'for traversingthe machine along the declqand said crawling gear may be reversible to enable the machine "to work ineither direction; Figs. 4 and 5 'illu'strate'a suitable form'o f carriage by way of-example. i The carriage 24 is supported on running wheels 27 and 28 mounted on axles 29 and 30 respectively. 'The axle 29 is fitted with clutchf nechanism 31 operated by external levers 32',the clutch mechanism 31 be 7 ing interposed between the axle '29 and a chain'or like drive 33' from a stub shaft 34 having a worm wheel '35 thereon which gears with a worm on a worm'shaft '36" driven in turn by a driving shaft 37. The shaft 37 may be driven in either direction from the motor ing38, 1

l8iby belt or, chain gear- To traverse the carriage across the deck or; floor from seam to seam, add t onalrunn ng wheels 39' may be -provided,'eccentrically mount d upon" shafts 40 adapted to belrotated by across-shaft 41 and operating han dle 42, so as to raise :or lowerthe wheels 39 and thus'cause them to lift the machineand its running wheels 27 and, 28clear" of the deck or lower the same into. contact there with. 'When themachine is raised, thewheels 39 maybe rotated bywheels or pini'ons 43 on a shaft 44, rotated by an external crank handle 45, the pinions 43 driving onepair of wheels 39 by, friction or' by means of teeth thereon. V j' V j In order to insure, perfectalinement during the traverse 'of'the machine alongthe deck, the machine may be fitted (as shown in Figs. 1 and3) with fore. and aft aliningl I guides or r0llers'46, preferably vertically'adjustable on' the machine frame and running" in the'seam or seamsin front ,ofand'in rear of the tool 5.
